WebMay 15, 2024 · 1. You need to use cvxpy operators on cvxpy variables, in other words you can't do np.matmul with a cvxpy variable. You can just use the * operator. cvxpy will treat this as matrix multiplication. Try this, C = np.random.randn (2, n) C * X. and you'll get: Expression (AFFINE, UNKNOWN, (2, 3)) Share.
